Hello:I am in Bangalore and am planning to switch from Airtel to BSNL thanks to Airtel's atrocious 3G pricing. I am just wondering how is BSNL's coverage in Bangalore. I am ok if the 3G coverage is a little patchy, but as long as 2G voice and Edge works seamlessly I'd be more than happy to migrate. I am more interested in the Outer Ring Road area around and inside Cisco/Intel/RMZ Ecospace campuses. I know that BSNL's coverage is very good in Rural areas, highways, etc. But given the fact that I will be spending most of the time within the city, I would require the services to be dependable inside office buildings, etc.Would appreciate your experiences. Thanks very much.
